Apple has a habit of sometimes rewriting one of its apps from the ground up, for reasons that aren't immediately obvious. This usually comes with a drastic reduction of features in the rewritten app, much to the chagrin of its users, before they gradually start adding features back in. The Keynote apps (for Mac and iOS) recently went through this cycle as well.
